I can't help you much because I have never owned the Durga but it appears that either it's lost it's plating on the table or someone has worked on the table, can't tell if what you call tape is something that TW did but its not there on the new Durga 4 by looking on his website.
I own a TW Mindi Abair and its is impeccably finished and the lig works fine so maybe yours has had a lot of use.
Which Durga is it 1,2,3 or 4?
